I just purchased Painter 2021 and discovered that the Art Pen rotation doesn't seem to work.
it is odd. @skipallen
did a demo with is art pen at the end of the video.
Drivers, maybe ?
Skip, thanks. I had to change the expression setting for rotation. It is possible that previous version defaulted to that for the Art Pen, or I just did not remember modifying the settings.
At least in Corel Painter 2019, you have to explicitly set it for every brush, and I suspect 2021 probably overrode your prior settings.
Some brushes are set to Art Pen, others are not. It just depends...most important thing it check the settings...for most brushes this is the "Angle" panel, for other brushes is may be in the "RealBristle" panel.
